Bertrand Russell's message to future generations (1959). Timeless advice and as relevant as ever. Wish more people would live by this.
What makes a good school system?
Not just PISA scores, but also equity, belonging, bullying, teacher support, classroom discipline, teacher shortages and resources.
Looking at all of them together across 39 countries changes the picture.

This is Évariste Galois (1811-32), a French mathematician and child prodigy who shaped the history of #mathematics. If you think life as a mathematician must be boring, you are wrong. Galois is one of many examples of the passion and drama surrounding mathematicians. In 1832, at the age of just twenty, Galois fell head over heels in love and accepted the challenge to a pistol duel, which he – probably with good reason – was so convinced he would lose that he stayed up all night the night before writing down all his mathematical theories. Galois was shot in the stomach by his rival and died the next day in a Paris hospital with his younger brother by his side. His last words were: "Don't cry, Alfred. I need all my courage to die at 20.” Before then, he just managed to change the course of the history of mathematics.

The world is awful. The world is much better. The world can be much better. All three statements are true at the same time. ourworldindata.org/much-bett… @MaxCRoser
